capable of supporting with a roll of tape so that it is readilyrotatable within the carton and so that it may be readily dispensed.

A feature of the present invention resides in the provision of a tapeholding carton comprising a rectangular sleeve which may if desired beprovided with open ends. A flap is cut from each of the panels overlyingthe hollow cyhndrical core of the tape roll. The sides of the flaps arecurved in form so that when the flap is bent to extend diagonally intothe core of the roll, the side edges of the flap will bear against theinner surface of the core. Accordingly, the tape roll ispermitted torotate about the edges of the flap which are substantially arcuate inform.

A feature of the present invention resides in the provision of a simpletape roll holder in which the two flaps are held in proper relationmerely by overlapping the ends of the flaps so that the end of each flapprevents the other flap from returning to the plane of the panel fromwhich it is cut. Thus by flexing the flaps to the extent necessary sothat the ends will overlap, the flaps will automatically remain engagedand form a substantial support for the roll of tape.

A feature of the present invention resides in the fact that the edges ofthe flaps are cut in'such a manner that when the flaps are diagonallyextending and in overlap ping relation they forrna circular outline whenviewed axially of the tape roll, In other words, the edges of the flapsform a circular outline when they are flexed into angular relation fromthe panels from which they are cut and are overlapped.

These and other objects and novel features of the present invention willbe more clearly and fully set forth in the following specification andclaims.

In the drawings forming a part of the specification.

FIGURE 1 is a perspective View of the tape roll holder in readiness foruse.

FlGURE 2 is a sectional view through the carton and through the taperoll showing the position of the flaps when they are overlapped.

FIGURE 3 is a sectional view, the position of the section beingindicated by the line 3-3 of FIGURE 2.

FIGURE 4 is a diagrammatic view of the blank from which the carton isformed.

The form of carton which is employed is indicated in general by theletter A and is shown in its set up form in FIGURE 1. The carton A isdesigned to accommodate a tape roll which is indicated in general by theletter B. The tape roll B in ordinary practice includes a hollowcylindrical core having the tape llwound spirally thereupon. The corelit and the tape 11 is preferably substantially equal to the width ofthe carton so that the roll is held from axial movement.

The carton A is shown as including a side wall panel 12, an end wallpanel 13, a side wall panel 14, and an end wall panel 1% which arefoldably connected along parallel fold lines. The panels 12 and 13 areconnected 3,014,573 Patented Dec. 26, 1961 iee by a fold line 16, thepanels 13 and 14 are connected along a fold line 17, and the panels 14and 15 are .COIle nected along a fold line 15?. A glue flap 20 isfoldably connected to one end panel of the series such as the panel 12along a fold line 21, and this glue flap 20 is overlapped with the endwall 15 and is adhered thereto. Also in the preferred form ofconstruction, one end wall such as the end wall 13 is notched along itsupper edge as indicated at 22 or in other words is not quite as high asthe remaining panels. A metal cutting strip 23 having a serrated edge24is provided with prongs or cars 25 which are bent from the plane ofthe strip 23 and are forced through the end wall 13 to secure thecutting edge with the serrations 24 at substantially the level of theremaining walls 12, 1d, and 15. In dispensing the tape, a portion of thetape is unrolled from the roll B, pulled over the serrated edge 24, andtorn off.

Each of the side wali panels 12 and 14 is provided with a flap which maybe folded out of the plane of the panels from which they are cut. Withreference to FIGURE 4 of the drawings, the circular broken lines 26 and27 indicate the inner diameter ofthe tape roll core 10. The flaps 29 and39 which are formed in the panels 12 and 14 respectively are foldablyconnected to these panels along parallel lines of told 31 and 32respectively which are substantially chords of the circular outlines 26and 2'7. In View of the fact that the flaps 29 and 30 ex tend diagonallythrough the core 10, these flaps must have their widest points somewhatoitset from the axis of the core so that when these flaps are foldeddiagonally, the widest points will be at the center of the core.Accordingly, the arcuate edges 33 and 34 extend from the ends of thechord 3-2 along the radii 3S and 36 respectively, which are of slightlygreater radius than the radius of the circle 27. The arcuate edges 37and 39 are similarly out along a radius which is somewhat greater thanthe radius of the circle 26. As a result, when the flaps are folded'intodiagonal relation as indicated in FIGURE 2 of the drawings, they providea circular outline when viewed axially of the tape roll core.

- The ends ofthe flaps 29 and 30am defined by cut lines 40 and 41parallel to the fold lines 31 and 32. The fold line 40 connects the endsof the cut lines 37 and 39 while the out line d1 connects the ends ofthe cut lines 33 and 34. The flaps are of a proper length to slightlyoverlap when in the diagonal position indicated in FTGURE 2.

The tape is assembled in the carton A by folding the carton intorectangular form and inserting the tape roll B into the sleeve; Theflaps 2-9 and 36 are then iiexed down into the tape roll core, the flapsflexing into somewhat concave form during this process. When the ends 40and 41 of the flaps are depressed sutficiently so that the end of oneflap is clear of the other, the pressure is released and the flaps arepermitted to flex back toward the plane or" the panel from which theyare out. This flexing action is limited by the engagement of the ends ofthe flaps as they flex back into contact. When overlapped in the mannerillustrated in FIGURE 2 of the drawings, neither of the flaps will ilexback into the plane of the panel from which it is out due to this innerengagement.

Once the tape roll is inserted and the flaps are flexed into theposition illustrated in FlGURE 2, the tape roll is in readiness for use.The end of the tape is unrolled from the roll and pulled over theserrated edge 24 of the cutting strip 23. This permits the tape to beunrolled to the desired extent and cut off to provide the proper lengthsof tape.

In accordance with the patent statutes l have described the principlesof construction and operation of my tape roll holder.

And while I have endeavored to set forth the best embodiment thereof, Idesire to have it understood that obvious changes may be made within thescope of the following claims without departing from the spirit of myinvention.

I claim:

1. A tape roll holder for holding a cylindrical roll having a hollowcylindrical core, the holder including a sleeve including fourrectangularly arranged panels, two of which overlie the ends of saidcore, and a flap hingedly connected to each of said two panels alongparallel lines of fold on opposite sides of the center of the core andextending beyond the center of the core, said flaps having edgesdiverging from said fold lines and engaging the walls of the core whenfolded at an acute angle to the planes of the panels from which they arefolded, said flaps extending into overlapping relation.

2. The structure of claim 1 and in which the overlapping ends of theflaps hold the -fiaps from returning to the planes of the panels fromwhich they are folded.

3. The structure of claim 1 and in which the side edges of the flaps arecurved to fit against the walls of the core when the flap ends are inoverlapping relation.

4. A tape roll holder for holding a cylindrical roll having a hollowcylindrical core, the holder including a sleeve including fourrectangularly arranged panels, two of which overlie the ends of saidcore, and a flap hingedly connected to each of said two panels alongparallel lines of fold on opposite sides of the center of the core, theflaps extending beyond the core center and being folded into the core toextend diagonally across the core, the ends of the flaps overlapping andthe ends of the flaps interengaging to hold the same from folding backto the plane of the panels from which they are connected, and edges onsaid flaps engaging the inner surface of said core.

5. The structure of claim 4 and in which the flap edges are curved tofit the contour of the core surface when in overlapped relation.
